Philippines Environment Monitor: Water Quality

Poor water quality has large economic and quality of life costs, in terms of health impacts and foregone revenues. According to the Philippine government's monitoring data, just over 36 percent of the country's river systems are classified as sources of public water supply and that up to 58 percent of groundwater sampled is contaminated with coliform and needs treatment. Approximately 31 percent of illnesses monitored for a five-year period were also caused by water-borne sources, and many areas are experiencing a shortage of water supply, during the dry season.
